Exfm had an interesting take on music discovery based on scanning blogs for MP3s that could be imported into a cloud-based player. Things seemed to be going fine as the company launched apps, plugins, and an API. Then it abruptly shut down in January. The company has hinted in the interim that something was going to happen, and now we know what's up—Exfm is being bought by Rhapsody.

T-Mobile has just announced their plans for Uncarrier part 5. The first big move of the T-mo's latest effort to shake up the wireless industry is the announcement of Test-Drive, a service through which users can get an iPhone 5S for seven days to take T-Mobile's "data strong" network for, well, a test drive. There's no down-payment, no charge, no nothing. Just get the device, try out the network, and return it at a store when you're done.

As if there weren't enough contenders out there for music subscription service, Slacker Radio has updated its business model. You can still get the standard ad-supported radio station features that were always available. However the company has added a Spotify-like buffet option for $10/month. Pony up the dough and you can remove all ads and listen to as many tracks as you want.

The combination is pretty powerful, as one of the biggest complaints over Spotify is its discovery problems.

While services like Spotify and Rdio may steal the spotlight most of the time, there are other streaming subscription services out there. Related: we need a better name than "streaming subscription services." Rhapsody, originally founded by Real Networks and since become an independent entity, has a pretty impressive library that users can now download for offline playback. An essential feature for a modern cloud music player. Update: To clarify, it's the ability to download songs on an individual or per-album basis that is new.

This morning, I noticed an interesting thread in the EVO subsection of the XDA forums that claimed to be able to fix music streaming (which was broken in some apps after the latest OTA), while boosting 3G speeds by .2 to .6 Mbps. As the process is very simple and easily reversible, I gave it a go - but decided that I was going to use SpeedTest to benchmark the changes.

Looks like the Rhapsody app has just dropped on the market, only... you can't find it by searching. However, barcode scanners work, so we're not really sure what's going on. The app itself seems to feature, well, just about what you'd expect:

*Download and offline playback of your playlists! - Download playlists and manage your downloads through the My Playlists menu. - New toolbar with download and other options on the playlist screen.
